Mapzen is also excellent (although definitely less mature than Mapbox), and a huge chunk of their stack is open source.

  At Mapzen, all our code is open source, from front-end UIs to back-end "glue." Have a look at: - web and mobile SDKs: http://github.com/mapzen/ http://github.com/mapzen/ - map rendering library: http://github.com/tangrams http://github.com/tangrams - map tiles: https://github.com/tilezen/ https://github.com/tilezen/ - routing/navigation: https://github.com/valhalla/ https://github.com/valhalla/ - public transit: https://github.com/transitland/ https://github.com/transitland/ - search/geocoding: http://github.com/pelias http://github.com/pelias - gazetteer: https://github.com/whosonfirst https://github.com/whosonfirst FWIW, we do have a few private repos, to protect some ops internals as well as upcoming blog posts. (I work at Mapzen -- and am also a happy user of Mapbox's open-source libraries.)

    Yup. I've checked out a bunch of those – and have actually contributed to pelias/api (and a dependency, addressit). Everything I've seen so far has been clean and pretty easy to follow. Really appreciate the work you all do. I'm a very happy Mapzen customer.

    Mapzen is an awesome company. I'm excited to see what comes of OpenTraffic, a Mapzen-sponsored, open-source traffic speed data set: https://github.com/opentraffic/ https://github.com/opentraffic/
